Is there a similar series or a sequel?

I just finished watching Pretty Little Liars on Netflix. Now I don't know what to watch next. Is there maybe a series similar to this or a sequel (after season 7 ends)?

I think it's a real shame that it's over now. I would love to know how it goes on afterwards.

There's Pretty Little Liars: The Perfectionists, which is the sequel with other actors (except Mona, Alison and someone else). Where you can watch it, I have no idea, if you have found out where to watch it, please let me know.

You can currently only watch the series on TVnow but the series was discontinued after a few episodes

As I said, there are only Pretty Little Liars The Perfectionists but the series can only be streamed on TVNOW and it was discontinued after a few episodes
